摘要: 利用无穷维KAM理论, 证明一维非线性波动方程在反周 期边界条件下存在Whitney意义下光滑的小幅拟周期解, 并在相应无穷维动力系统中这些解形成一个有限维的不变环面.

关键词: 波动方程, 反周期边界, 无穷维KAM理论, 拟周期解

Abstract: This paper concerns one dimensional (1D) nonlinear wave equations. We can prove the existence of a Whitney smooth of smallamplitude quasiperiodic solution under the antiperiodic boundary conditions. The proof is based on an infinitedimensional KAM (KolomogorovArnoldMoser) theorem.

Key words: wave equation, antiperiodic boundary, infinite KAM theorem, quasiperiodic solutions
